Description
Wärmetauscher mit an lotrechten Wandrohren eines Heizgaszuges angeschlossenen. Röhrbündeln . _ ..: . _ Die Erfindung betrifft einen Wärmetauscher, bei dem eine Flüssigkeit im Innern von einzelnen parallel zueinander liegenden, zu Rohrbündeln zusammengefaßten und einer Beheizung ausgesetzten Rohren, welche im Arbeitsmittelstrom parallel geschaltet sind und deren der Querströmung des Heizmittels ausgesetzte einfache Rohrstrecke ein Mehrfaches von der dem Parallelstrom ausgesetzten Rohrstrecke beträgt, erwärmt oder verdampft wird und wobei die Rohrbündel an lotrechten öder annähernd lotrechten, die Wände eines Heizgaszuges verkleidenden Rohren angeschlossen sind.Heat exchangers connected to vertical wall pipes of a heating gas flue. Tube bundles. _ ..:. _ The invention relates to a heat exchanger in which a Liquid inside of individual tube bundles lying parallel to one another combined pipes exposed to heating, which are in the working medium flow are connected in parallel and exposed to the cross flow of the heating medium simple pipe section a multiple of the pipe section exposed to the parallel flow is, is heated or vaporized and wherein the tube bundle at vertical barren connected approximately perpendicular pipes lining the walls of a heating gas flue are.
Es ist bekannt, bei Wärmetauschern jeweils einseitig geschlossene oder einzelne U- oder V-förmig gebogene Rohre von Wandrohren in den Gasstrom hineinragend anzuwenden. Eine derartige Ausbildung ergibt nur ,eine geringe wärmeaufnehmende Fläche, weshalb man zur Vergrößerung der Fläche zu komplizierten Rohrformen überging. Beispielsweise wurden die Rohre in Form eines seitwärts liegenden W oder in Schraubenlinien mit mehr oder minder langen geraden Strecken gebogen. Derartige Rohrformen sind nicht nur schwer herzustellen, sie haben auch einen erhöhten Druckabfall.It is known that heat exchangers are closed on one side or individual U- or V-shaped bent pipes from wall pipes protruding into the gas flow apply. Such a training results only in a low heat-absorbing Area, which is why complex tube shapes were used to increase the area. For example, the tubes were in the shape of a sideways W or in helical lines curved with more or less long straight stretches. Such tube shapes are Not only are they difficult to manufacture, they also have an increased pressure drop.
Bei einem weiteren Wärmetauscher kommen U-förmige, in einer Ebene liegende, an einem zugehörigen Wandrohr angeschlossene Rohre zur Anwendung, deren dem Gasstrom ausgesetzte waagerechte Rohrstrecken im Verhältnis zu den parallel angeströmten Rohrstrecken kurz sind, was einen ungünstigen Wärmeübergang zur Folge hat.Another heat exchanger is U-shaped, in one plane lying pipes connected to an associated wall pipe for use, whose horizontal pipe sections exposed to the gas flow in relation to the parallel sections are short, which results in an unfavorable heat transfer Has.
Es sind jedoch auch Wärmetauscher bekanntgeworden, bei welchen ein derartiges, aus U-förmigen Rohren gebildetes Rohrbündel lange, der Querströmung der Gase ausgesetzte Rohrstrecken aufweist. Die U-förmigen Rohre sind hierbei im Arbeitsmittelstrom parallel geschaltet.However, there are also heat exchangers known in which a such a tube bundle formed from U-shaped tubes long, the cross flow which has pipe sections exposed to gases. The U-shaped tubes are here in Working medium flow connected in parallel.
Ferner ist es nicht neu, bei Wärmetauschern mehrere Rohrgruppen hintereinanderzuschalten, die vom Arbeitsmittel nacheinander durchströmt werden.Furthermore, it is not new to connect several pipe groups in series with heat exchangers, through which the work equipment flows one after the other.
Weiter ist es bekannt, in die Wandrohre eines Wärmetauschers, von denen U-förmig gebogene Rohre ausgehen, die in einen Dampfraum münden, eine Drosselstelle einzusetzen, die das Aufsteigen von Dampf erlaubt, eine absteigende Wasserströmung dagegen verhindert.It is also known, in the wall tubes of a heat exchanger, from where U-shaped bent pipes run out, which open into a steam chamber, a throttle point to use that allows steam to rise, a descending flow of water against it prevented.
Bei einer weiteren Wärmetauscherfläche sind haarnadelförmig gebogene Rohre an ein Rohr angeschlossen, das mittels einer Scheibe in zwei Kammern geteilt ist, die durch ein Loch in der Scheibe miteinander in Verbindung stehen, so daß Dampfwassergemisch unmittelbar in die untere Kammer abströmen kann, ohne die Rohre der Wärmetauscherfläche durchströmen zu müssen.In the case of a further heat exchanger surface, they are curved in the shape of hairpins Pipes connected to a pipe that is divided into two chambers by means of a washer which are in communication with each other through a hole in the disc, so that Steam water mixture can flow directly into the lower chamber without the pipes having to flow through the heat exchanger surface.
Der Erfindung liegt die Aufgabe zugrunde, einen Wärmetauscher zu schaffen, bei dem-eine große Wärmetauscherfläche auf vorgegebenem kleinem Raum bei Vermeidung komplizierter Rohrformen--untergebracht werden kann. Hierbei wird angestrebt, große; der Querströmung des Heizmittels ausgesetzte Rohrstrecken zu verwenden, um einen guten Wärmeübergang zu erreichen. Ferner soll eine Verringerung der Temperaturunterschiede in den einzelnen Rohren der Rohrbündel erzielt werden, um damit eine gleichmäßige, Aufwärmung des Arbeitsmittels zu erhalten: Ein geringer Druckabfall in den einzelnen Wärmetauscherflächen ist ein weiteres Ziel der Erfindung, wie auch eine häufige und intensive Durchmischung des Arbeitsmittels. Weiterhin soll eine leichte Ausbaubarkeit etwa schadhaft gewordener Rohre gesichert sein.The invention is based on the object of creating a heat exchanger, in which a large heat exchanger surface in a given small space if avoided more complicated pipe shapes - can be accommodated. The aim here is large; to use the cross flow of the heating medium exposed pipe sections to a to achieve good heat transfer. Furthermore, the aim is to reduce the temperature differences can be achieved in the individual tubes of the tube bundle in order to achieve a uniform, To maintain warming up of the work equipment: A small pressure drop in the individual Heat exchange surfaces is another object of the invention, as well as a common one and intensive mixing of the working medium. Furthermore, it should be easy to expand any damaged pipes must be secured.
Zur Lösung der gestellten Aufgabe wird für einen Wärmetauscher der eingangs. genannten Gattung vorgeschlagen, daß die lotrechten oder annähernd lotrechten Rohre mit in. Abstand voneinander liegenden an sich bekannten Drosselstellen. versehen sind und die in an sich bekannter Weise im Arbeitsmittelstrom hintereinandergeschalteten Rohrbündel an den lotrechten Rohren derart angeschlossen: sind,- daß -die Austrittsenden eines ersten Rohrbündels und die Ein trittsenden des darauffolgenden Rohrbündels in einen von Drosselstellen begrenzten Abschnitt des zugehörigen lotrechten Rohres münden.To solve the problem, the is for a heat exchanger at the beginning. mentioned genus suggested that the perpendicular or approximately perpendicular Pipes with throttling points which are known per se and which are located at a distance from one another. Mistake and which are connected in series in the working medium flow in a manner known per se Tube bundles are connected to the vertical tubes in such a way: - that - the outlet ends a first tube bundle and the A occurs ends of the subsequent tube bundle into a section of the associated vertical pipe that is limited by throttling points flow out.

sind, ein. guter Wärmeübergang gesichert
F i g. 4 zeigt als Anwendungsbeispiel eines Wärmetauschers einen Abhitzekessel. Hierbei sind das im höchsten und das.-im niedrigen Temperaturbereich liegende Rohrbündel 1 . am -gleichen .Seitenwandrohr angeschlossen, während die im mittleren Temperaturbereich liegenden Bündel ebenfalls an einem gleichen Rohr angeschlossen: -sind. Damit ergibt sich am Ende der lotrechten Rohre eine für beide Zugseiten etwa gleiche Temperatur der Teilströme.F i g. 4 shows a waste heat boiler as an application example of a heat exchanger. These are tube bundles 1 in the highest and that in the low temperature range. connected to the same side wall pipe, while the bundles lying in the middle temperature range are also connected to the same pipe: are. This results in a temperature of the partial flows that is approximately the same for both sides of the train at the end of the vertical tubes.
